This review article explores the psychological characteristics, comorbid mental disorders, and psychosocial assessments throughout the solid organ transplant journey, spanning the pre-transplant, peri-transplant, and post-transplant phases for transplant recipients. The psychological burden and anxiety in the pre-transplant phase are high for organ failure patients with complex physical difficulties who are deciding to undergo transplantation and are on the waiting list. The pre-transplant psychosocial evaluation covers various aspects, including the patient's readiness, awareness of, and commitment to transplant treatment, medical compliance, psychopathological conditions such as cognitive function and personality disorders, lifestyle factors, including substance abuse, as well as various psychosocial factors like social support. During the peri-transplant phase, mental health problems such as postoperative delirium should be carefully recognized and addressed. After transplantation, it is essential to assist patients in coping with the various stressful experiences they encounter, manage psychiatric symptoms such as depression, anxiety, and insomnia, and improve treatment adherence and quality of life during long-term care for the transplanted organ. Managing psychiatric problems in post-transplant patients requires a deep understanding of immunosuppressant medications and a keen awareness of associated risks, including adverse effects and potential drug interactions. This comprehensive review emphasizes the significance of proactive mental health care and psychosocial evaluation, highlighting the necessity of a multidisciplinary approach to enhance the quality of life and overall success of transplant patients throughout all phases of transplantation.

최근 반려동물 시장 규모가 커짐에 따라 반려동물 관련 사회적 문제도 대두되고 있다. 대표적으로 반려견 물림 사고, 유기견 문제, 안락사, 동물 학대 등이 있다. 대안으로 반려동물 관련 방송, 교육 앱 등 다양한 방식의 훈련 프로그램이 제공되고 있지만, 무엇을 먼저 가르쳐야 할지 모르는 초보 보호자들에게는 그리 효율적이지 못하다. 비교적 접근성이 용이한 훈련 앱이 다수 배포됐지만, 아직 사용자가 직접 훈련을 체험하며 익히는 방식의 앱은 부족한 실정이다. 이에 본 논문에서는 유니티 엔진을 활용해 더욱 효율적인 AR 기반의 반려견 훈련 모바일 앱을 제안한다. 사용성 평가 결과, 기존에 부재했던 요소의 추가로 사용자들 흥미도는 증대했고, 훈련 몰입감까지 제고되어 학습 효과가 향상됐다. 향후 개발 및 양산 검증까지 거쳐 배포된다면 반려동물 입양 계획을 세운 초보 보호자나 기존 보호자들에게 효과적인 훈련 앱이 될 것으로 기대된다.

The type-1 cannabinoid receptor (CB₁R) is a potential therapeutic target in several pathological conditions, including neuropsychological disorders and neurodegenerative diseases. Owing to their structural diversity, it is not easy to derive general structure-activity relationships (SARs) for CB₁R ligands. In this study, CB₁R ligands were classified into six structural families, and the corresponding SAR was determined for their affinities for CB₁R. In addition, we determined their functional activities for the activation of extracellular signal-regulated kinases (ERKs). Among derivatives of indol-3-yl-methanone, the highest ligand affinity was observed when a pentyl and a naphthalenyl group were attached to the N1 position of the indole ring and the carbon site of the methanone moiety, respectively. In the case of adamantane indazole-3-carboxamide derivatives, the presence of fluorine in the pentyl group, the substituent at the N1 position of the indazole ring, strongly increased the affinity for CB₁R. For (naphthalen-1-yl) methanone derivatives, the presence of 4-alkoxynaphthalene in the methanone moiety was more beneficial for the affinity to CB₁R than that of a heterocyclic ring. The functional activities of the tested compounds, evaluated through ERK assay, were correlated with their affinity for CB₁R, suggesting their agonistic nature. In conclusion, this study provides valuable insight for designing novel ligands for CB₁R, which can be used to control psychiatric disorders and drug abuse.

Three hundred sixty-two(male 131, female 231) elderly aged over 65 in Chungb- uk area were interviewed to determine the disease states and drug usage patterns. The prebalence of disease was 78% and women reported more chronic diseases(83%) than men(71%). Elderly who live with spouse and have an occupation have a lower rate of disease. Average number of diseases of the elderly was $1.8\pm{1.1}$, and women$(2.1\pm{1.3)}$ have significantly higher average number of diseases than that of men$(1.4\pm{0.7)}$. Also the elderly in urban areas$(2.1\pm{1.4)}$ have significantly higher number of diseases than that of the elderly in rural areas$(1.6\pm{0.9)}$. Arthritis, hypertension, cardiovascular and gastric diseases were the most frequently listed chronic diseases in order for both men and women. Anemia and fracture of bone were relatively higher in women than in men. Particularly, the arthritis of the urban elderly have a rate of 1.5 times higher than that of the rural elderly. Fifty-two percent of the elderly were currently using drugs ; among drug users 71.2% used prescription drugs and 20.5% used nonprescription drugs. The average number taken per person was 2.1$\pm$1.4 and there was no sex or age difference. However, the elderly in rural areas $(2.7\pm{1.7)}$ consumed a significantly higher number of drugs than those in urban areas$(1.7\pm{0.7)}$. The average number of prescripti- on drugs taken was 2.0$\pm$1.4 while the average of nonprescription drugs taken was $(1.3\pm{0.6)}$. Analgesics and antihypertensive drugs were most commonly used. Vitamin and analgesics were the most frequently used self-prescribed drugs. It was noted that potential adverse drug interaction by concominant drug consumption for arthritis and antihypensive drug, abuse of digestants and antiacid without treatment of the underlying disease, and misuse of quick-acting bowel medications were problematic for the elderly. In addition drugs used for the elderly have some adverse effect on the digestive system. The types and composition of drugs used by the elderly were identified and presented. Medication compliance was poor and 13.5% reported adverse reactions such as edema, heartburn, nausea, and difficulty with eating. Seventeen percent of the elderly obtained drugs arranged by those other than medical staff. Also, even among those elderly who obtained drugs prescribed by a doctor, 69.1% of subjects had not receive instruction about potential adverse reactions. These results suggest that nutritional problems related to drug usage might exist and so dietitians, either individually or as members of health teams, need to have a better understanding of drug-nutrient interaction and closer supervision, and drug information/education service should therefore be provided to prevent or minimize adverse drug reaction in elderly users of medication.

Synthetic cannabinoids (CBs) such as the JWH series have caused social problems concerning their abuse liability. Because the JWH series produces euphoric and hallucinogenic effects, they have been distributed illegally under street names such as "Spice" and "Smoke". Many countries including Korea have started to schedule some of the JWH series compounds as controlled substances, but there are a number of JWH series chemicals that remain uncontrolled by law. In this study, three synthetic CBs with different binding affinities to the $CB_1$ receptor (JWH-073, 081, and 210) and ${\Delta}^9$-tetrahydrocannabinol (${\Delta}^9$-THC) were evaluated for their potential for psychological dependence. The conditioned place preference test (unbiased method) and self-administration test (fixed ratio of 1) using rodents were conducted. $K_i$ values of the three synthetic cannabinoids were calculated as supplementary data using a receptor binding assay and overexpressed $CB_1$ protein membranes to compare dependence potential with $CB_1$ receptor binding affinity. All mice administered JWH-073, 081, or 210 showed significantly increased time spent at unpreferred space in a dose-dependence manner in the conditioned place preference test. In contrast, all tested substances except ${\Delta}^9$-THC showed aversion phenomenon at high doses in the conditioned place preference test. The order of affinity to the $CB_1$ receptor in the receptor binding assay was JWH-210 > JWH-081 >> JWH-073, which was in agreement with the results from the conditioned place preference test. However, no change in self-administration was observed. These findings suggest the possibility to predict dependence potential of synthetic CBs through a receptor binding assay at the screening level.

여드름은 만성 염증 질환으로 주로 청소년기에 발생하는 것으로 알려져 있으나 대기오염, 약물 남용 등의 원인에 의해 아동기 및 성인기에도 나타날 수 있다고 알려져 있다. 여드름을 유발하는 정확한 원인은 밝혀져 있지 않으나 한 가지 원인보다 스트레스, 호르몬의 변화, 유전, 외부 환경 등 다양한 요인들이 복합적으로 작용한다고 여겨지고 있다. Propionibacterium acnes (P. acnes)는 여드름을 유발하는 균으로 모낭 내에 상주하여 피지의 중성지방을 분해하고 유리 지방산을 형성하여 모낭 내 염증을 유발한다. 따라서 피지의 생성 증가는 P. acnes의 생존에 좋은 영향을 주고 피부에서 염증반응을 유발하는 monocytic cell의 활성화와 염증성 사이토카인(pro-inflammatory cytokine)의 증가를 유발한다. 따라서 여드름 치료를 위해서는 P. acnes의 증식 억제 및 염증반응을 최소화하는 것이 중요하다. 본 논문에서는 유칼립투스(Eucalyptus globules) 추출물이 P. acnes에 의한 염증반응에 나타내는 효과를 확인하고자 하였다. 유칼립투스 추출물 처리는 P. acnes가 유도하는 염증 매개자로 알려진 $TNF-{\alpha}$, $IL-1{\beta}$, IL-2와 인플라마좀 복합체인 NLRP3의 유전자 발현을 효과적으로 감소시키는 것을 확인하였다. 뿐만 아니라 염증성 사이토카인의 유전자 발현에 중요하다고 알려진 전사인자(transcription factors) $NF-{\kappa}B$와 NFAT의 활성 역시 유칼립투스 추출물을 처리하였을 때 감소하는 것을 알 수 있었다. 따라서 본 논문을 통해 유칼립투스 추출물이 P. acnes에 의해 초래되는 여드름의 치료 보조제로 사용될 수 있으며, 천연 추출물의 사용이 항생제 장기 복용으로 인해 유발되는 항생제 내성을 해결하는 좋은 대안이 될 것이라고 예상할 수 있다.

AUDIT-K(한국형 알코올 중독 간이선별 검사법)을 이용하여 일상적으로 생활하고 있는 상당수의 잠재적인 위험 음주자들을 선별 할 수 있었으며 연령, 종교, 결혼여부, 직업, 소득음주사망 가족력, 음주시작 연령, 흡연, BMI(체질량지수)는 통계적으로 유의한 차이가 없었으며, 학력, 음주기간만 통계적으로 유의하였다. 이러한 결과는 교육을 더 받은 사람의 남성이 알코올 소비가 더 높다고 한 선행연구와 부합하는 결과를 나타내었으며 교육수준 또한 무엇을 어떻게 배웠는가에 따른 차이를 살펴 볼 필요가 있음을 시사하며, 교육에 따른 알코올 소비도 각각 다른 결과를 나타냄을 알 수 있다. 또한 나이가 적을수록 술을 많이 마시면 음주기간이 길어질 것이고 기존의 음주시작 연령에 대한 연구와 일치하는 결과가 나타났다. 본 연구에서는 음주 기간이 알코올 사용 장애의 가장 큰 요인이었으며 음주 기간을 단축하기 위한 방법으로는 음주 시작 연령을 최대한 늦출 수 있는 국가 정부 제도의 대책 및 교육이 필요하다고 생각된다.

During the past 10 years, concern for community people's health has increased together with the changes. Public health policies and studies for community people's health, however, have influenced those in childmaternal health care to want more general coverage and studies of health and wellness. Particularly, the study of community people's health in the extent an island area is almost rare as that personal and the material benefits in this area are lacking of community people's work is large, and the basic elements of living, such as diet and elimination, are irregular due to the schedule of the tide. Thus, there are many potential health problems. In this regard, the study attempted to understand the health problems of island community people and to provide a basis for developing health promotion and health education programs. In collecting data for the study, face to face interviews were made through a structured questionnaire from October 1 to December 30, 1996. Collected data were analyzed with the SAS statistics program, descriptive statistics, t-test and ANOVA. Subjects' health status was examined by classifying into such categories as their health perception, complaints of health problem, related lifestyle, psychosocial health staus, the result of examination is as follows; 1. For subjects' health perception, 26.9% of the subject answered not sick, but not so healthy'; 30.9% thought they were healthy, while 22.9% answered that they were not healthy. 2. For the health problem complaints many complained of pains in their muscles and skeletal system, especially knee joint pain. Women's health problems related with breast and the reproductive system included 52.3% of cases doing breast self examination, while 56.55% received the cervical cancer screening test. In men's health problems, 44.2% of subjects answered that they have moderate to severe BPH(Benign Prostatic Hypertrophy) symptom. 3. There were statistically a significant difference in the degree of physical health according to marital status(p=0.0028), occupation(p=0.0442), income(p=0.0357). 4. For stress status, 17.2% was to need the intervention, 50.2% was to need observation. 5. The mean score of self-esteem was 27.7 showing a relatively high score. 6. For the rate of smoking, 37.7% used to smoke, while 28% used to take alcohol. 7. The rate of substance abuse was 45.9% of subjects. 8. Most of subjects' health behaviors included most of the acupuncture (52%). 9. The rate of subjects receiving comprehensive medical testing was 34.36% while 34.78% did after care managing behavior. 10. For the obesity grade, 53% is normal weight, low-weight 32.8%, obesity 33%. 11. For nutrition status, 78.7% illy balanced to need intervention of nutritional education. 12. For 78.7% of subjects, muscle strength and 40.7% of stretching were not good enough to need health education on physical exercises. Therefore, based on the results, appropriate health education programs need to be developed to promote health of community people on an island.

Major depressive disorder is a leading cause of disability in more than 280 million people worldwide. Monoamine-based antidepressants are currently used to treat depression, but delays in treatment effects and lack of responses are major reasons for the need to develop faster and more efficient antidepressants. Studies show that ketamine (KET), a PCP analog, produces antidepressant effects within a few hours of administration that lasts up to a week. However, the use of KET has raised concerns about side effects, as well as the risk of abuse. 4 -F-PCP analog is a novel PCP analog that is also an NMDA receptor antagonist, structurally similar to KET, and might potentially elicit similar antidepressant effects, however, there has been no study on this subject yet. Herein, we investigate whether 4-F-PCP displays antidepressant effects and explored their potential therapeutic mechanisms. 4-F-PCP at 3 and 10 mg/kg doses showed antidepressant-like effects and repeated treatments maintained its effects. Furthermore, treatment with 4-F-PCP rescued the decreased expression of proteins most likely involved in depression and synaptic plasticity. Changes in the excitatory amino acid transporters (EAAT2, EAAT3, EAAT4) were also seen following drug treatment. Lastly, we assessed the possible side effects of 4-F-PCP after long-term treatment (up to 21 days). Results show that 4-F-PCP at 3 mg/kg dose did not alter the cognitive function of mice. Overall, current findings provide significant implications for future research not only with PCP analogs but also on the next generation of different types of antidepressants.
